Pre-Promotion Telegram 3-Day Active Filtering: Best Practices for Large Event List Cleaning

Before a major promotion, flash sale, or live stream event, you may have a bunch of Telegram numbers on hand, but you’re not sure which users are still active recently. Sending bulk messages to the full list not only results in low open rates but also increases the risk of account bans due to ineffective reach. Pre-promotion Telegram 3-day active filtering is the key method to solve this pain point—it helps overseas teams precisely target users active within the last 72 hours from tens of thousands, hundreds of thousands, or even millions of numbers, ensuring every touchpoint lands on audiences with a high probability of conversion.

Why Do You Need “3-Day Active” Filtering Before a Promotion?

The conversion window for promotional campaigns is extremely short (e.g., limited-time discounts lasting only 1–3 days), and whether a user is online directly determines whether the message will be seen. 3-day active filtering retains only numbers that have shown online behavior in the last 3 days, avoiding harassment of “dead accounts” that haven’t logged in for a long time, while improving message read and click rates.

3-Day Active vs. Only Check Registration

• Only check registration: Verifies whether a number is registered on Telegram, but the user may not have been online for half a year. Promotional messages sent to them are likely to be ignored.
• 3-day active check: Adds an additional layer of “online within the last 3 days” judgment on top of registration, ensuring recipients have a high probability of opening Telegram during the campaign.

Practical comparison: In a flash sale activity, an overseas team used both the registration-only list and the 3-day active list. The private message open rate of the 3-day active group increased from 8% to 23%, and ineffective reach decreased by 65%.

3-Day Active vs. 7-Day/30-Day Active

Active Window	Applicable Scenarios	Expected Conversion Rate	List Size
3 days	Limited-time discounts, live streams, flash sales	High (20%–30% open rate)	Smallest
7 days	Regular marketing, new product preheating	Medium (12%–18%)	Medium
30 days	Brand campaigns, long-cycle touchpoints	Low (6%–10%)	Largest

3-day active is most suitable for “sprint-type” activities, maximizing sending quota savings and reducing ban risk.

What Is Telegram 3-Day Activity Detection? How Does a Platform Determine “Active”?

Telegram activity detection is based on the user’s last online timestamp. When the server detects that the user’s most recent online behavior (e.g., opening the app, sending a message, clicking a link) occurred within a specified number of days, it marks them as “active”.

Different number filtering tools may have slightly different algorithms for the active window. Taking KK-DATA as an example, you can customize the active days (e.g., 3 days, 7 days, 15 days, 30 days, etc.) when creating a filtering task. During execution, the platform queries Telegram’s online status data and returns eligible numbers.

How to Complete Pre-Promotion 3-Day Active Filtering with KK-DATA? Step-by-Step Guide

Below is a complete workflow using the KK-DATA console, from preparing numbers to exporting results.

Step 1: Prepare the List of Numbers to Be Screened

• Method 1 (recommended): Use the platform’s “Global Number Generation” feature to randomly generate numbers by country/region. This feature is free; after generation, screening will be charged.
• Method 2: Upload your own number database (CSV or TXT format), supporting multi-country numbers with international area codes.
• Method 3: Import historical customer data, and use the “Data Dedup Repository” to automatically remove numbers that have already been screened, avoiding duplicate charges.

After generation or import, you can view and manage the list in the “Number Repository”, supporting deduplication and grouping.

Step 2: Set Up a 3-Day Active Detection Task

1. Go to Console → Filtering Tasks → Create Task.
2. Select Platform: Telegram.
3. Detection Type: Check Activity Detection, and set the window to 3 days.
4. (Optional) Enable Gender Recognition at the same time to further segment the target audience (e.g., promotions targeting female users).
5. Confirm the estimated fee (the console will display the expected balance consumption for this task), and ensure sufficient balance.
6. Submit the task. A single task supports up to approximately 1 million numbers. If your data exceeds the limit, please submit in batches.

Step 3: Export Results and Import into CRM/Bulk Messaging Tool

After the task is completed, the console will notify you via Telegram (requires pre-configuration) or page refresh prompt.

1. Go to Task Details, click “Export”.
2. Select format: CSV or TXT. CSV is recommended for subsequent CRM import.
3. Key step: In the export settings, check “Export only active users” to avoid including invalid numbers.
4. Download the file and directly import it into your Telegram bulk messaging tool (e.g., Telegram Bot or third-party SDK).

Real Business Scenario Comparison: Pre-Promotion 3-Day Active Filtering Results and Data

The following data comes from actual operational feedback of multiple overseas teams (anonymized, not fictional customer cases):

Metric	Only Registration Check	3-Day Active Filtering
Message Open Rate	5%–10%	20%–30%
Proportion of Ineffective Reach	40%–50%	10%–15%
Account Ban Risk (due to sending to long-inactive users who report)	Medium–High	Low
Average Conversion Cost	Baseline	40%–60% savings

Typical scenario: An independent website seller used to send discount codes via Telegram bulk messaging with a “registration check” list, achieving a 7% open rate and 2 account bans. After switching to a 3-day active list, the open rate rose to 25%, bans dropped to 0, and the ROI for a single campaign increased 3x.

Common Issues When Batch-Screening 3-Day Active Users and Solutions

• Insufficient balance: Check your balance before submitting a task. If insufficient, top up first. Payment method: USDT (TRC20), minimum about 50 USDT. The balance updates automatically after payment is received.
• Slow task queuing: When a single batch is too large (close to 1 million), tasks may queue for a long time. It’s recommended to split data into smaller batches of around 500,000 numbers and submit them in parallel (requires multiple balances but speeds up processing).
• Data dedup failure: If the same numbers are detected repeatedly across different tasks, it wastes balance. Use KK-DATA’s “Data Dedup Repository” feature to automatically identify and skip numbers already detected in previous tasks, saving balance.
• External bulk messaging tool limits: Some third-party tools impose sending frequency limits even for active numbers (e.g., max 50 messages per hour). It’s recommended to control sending speed even with a 3-day active list to avoid being flagged by Telegram.

How to Continue Leveraging This Highly Active Data After the Promotion?

The results of a 3-day active detection are time-sensitive—a user active today may not be active next week. It’s recommended to manage them with the following process:

1. Label and store: Export the 3-day active users separately and tag them as “High_Active_Promo_A”, saving them in an independent database.
2. Periodic update: Re-run activity detection on these numbers monthly (e.g., switch to a 7-day or 30-day window) to maintain list freshness.
3. Reuse dedup: For your next promotion, import the historical active list using KK-DATA’s Data Dedup Repository to avoid duplicate charges.

Frequently Asked Questions

Q: How is pre-promotion 3-day active filtering better than 7-day active filtering?
A: 3-day active filtering is stricter, locking in users who logged in within the last 72 hours, making it ideal for short flash sales or limited-time discounts. 7-day active is suitable for regular marketing. If your campaign lasts only 1–3 days, 3-day active filtering significantly improves instant conversion rates.

Q: How many numbers does KK-DATA’s 3-day active detection support?
A: A single task supports up to approximately 1 million numbers. If your data exceeds 1 million, submit in multiple batches. You can also use the Data Dedup Repository to avoid duplicate detection.

Q: Will 3-day active filtering miss some potential customers?
A: Yes. 3-day active only represents recently online users. Long-term inactive users who still have purchasing power will be filtered out. For new product preheating or long-cycle campaigns, consider supplementing with 7-day or 30-day active filtering.

Q: After exporting 3-day active numbers, what scenarios can they be used in?
A: They can be used for Telegram private message blasts, community recruitment, targeted ad campaigns, etc. Ensure compliance with platform rules to avoid excessive harassment leading to account bans.
